Checking for known tags:

No Data Found! - maybe not an LF tag?

You may try PR #887. This eliminates the Error message during 'lf search' and adds some reliability to Hitag functions in general.

On RDV4 with the standard antennas Hitag functions fail most of the time.

Please note that 'lf search' only detects Hitag2 but not HitagS.

887 is now merged to master. Just in case you don't know how to apply patches...

Any news?

I test your latest version on proxmark3 easy and rdv4. On the rdv4 i used the ex range antenna. The search function didnt work on both device. Tried the v3.1.0 and it's worked, but the tag must be in a exact position against the proxmark3.

v3.1.0
